Abstract

This is a pen cursor structure for a positional digitizing device such as a digitizing tablet or a pen-driven computer. It comprises a structure of an electrically insulating material having a plurality of areas for receiving and carrying electrical components, an inner structure having a plurality of electrical contacts disposed within the areas and a plurality of electrical traces interconnecting the plurality of electrical contacts. The structure is curved about a longitudinal axis to fit within an outer, hollow, pen-shaped housing.
